What is the mass of 2.65 millimoles of sulfur?

Divide this problem in to two steps: 1. Convert millimoles to moles. 2. Convert moles to grams.

1.

2.65 mlmol x 1mol/1000mlmol=.00265mol

2.

.00265mol x 32.065g/1 mol=.0850g S

Let me know if you need more explanation on why I used the conversions that I did.
